Question 1 5 pts The extinction coefficient for FD&C Blue Dye #1 is 138,500 cm-L/mol at 630 nm. A chemist collected the following data at 630 nm. She also found that the absorbance of an FD&C Blue Dye #1 solution of unknown concentration was 0.229. Use your graphing calculator to generate a standard curve from this data set, and use it to determine the concentration of the unknown solution. Express your answer in 10-5M (if your answer is 5.52x105M then...

In this lab we will be expressing rate as a change in
concentration of reactants over time. In order to calculate this,
we need to know the initial concentrations of our reagents after
they are combined but before the reaction occurs. This is a
dilution process. Recall that the calculation for a dilution is
accomplished using the relationship M1V1 = M2V2.
